Skill Pre-requisite

This should be easier than I'm making it. I'm trying to create a special ability that requires proficiency (or expertise) in a skill (in this case, Stealth). What do I put in the pre-requisites script to check for that?
 
You're looking for hero.tagis[ProfSkill.skStealth] <> 0. You may have to also look for hero.tagis[ProfDouble.skStealth] <> 0. I feel like I've seen it before where the Hero only has one of those, so test for both. It's been a minute since I did a pre-req so I don't know off the top of my head how to plug that in. But if you can find something with a pre-existing pre-req, it'll give you some direction.
 
Thanks! That put me on the right path. It needed to go in Expr-reqs, not Pre-reqs. I'm not sure how to OR hero.tagis[ProfDouble.skStealth] <> 0, but at least this is forward progress.
 
  • Set a variable.
  • If tag 1 is present, add 1 to the variable.
  • If tag 2 is present, add 1 to the variable.
  • If the variable > 0, the overall test is valid.

So I put something like this in the eval script:

Code: 
var SkillSt as number

if (hero.tagis[ProfSkill.skStealth] <> 0)
     then SkillSt += 1
endif

if (hero.tagis[ProfDouble.skStealth] <> 0)
     then SkillSt += 1
endif

And this in the Expr-reqs:

Code: 
SkillSt > 0

?
 
Correction: Do it in eval rules. Treat it like a regular script, but at the end, you're targeting "@valid = 1"

So:

if (SkillSt > 0) then
@valid = 1
endif
 
The full thing in the eval rule should be something like this:

Code: 
    <evalrule phase="Final" priority="100000" message="You must be proficient in Stealth."><![CDATA[
 var SkillSt as number

SkillSt = 0

if (hero.tagis[ProfSkill.skStealth] <> 0)
     then SkillSt += 1
endif

if (hero.tagis[ProfDouble.skStealth] <> 0)
     then SkillSt += 1
endif

   if (SkillSt > 0) then
   @valid = 1
 
if (@valid = 0) then
         @message = "You must be proficient in Stealth."
       endif
]]></evalrule>
 
I copy-pasted that directly into the rule, and got the same error: "Invalid use of reserved word 'if' in script."
 
That's....weird. It's a modified version of code from an eval rule already working perfectly fine in the pack. There's a fair amount of eval-rules in the TCOE content, which is what I pulled it from.
